HELMET.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed July 17, 1915. Serial No. 40,877.

for protecting the eyes and face from the effects of light and heat as in arc and gas welding, furnace work and the like.

The principal objects of thepresent invention are to provide a helmet, the shield of which may be said to'be automatic in its operation because the wearer by a toss of his head may cause the shield to cover' or uncover his face, thus leaving his hands free for use in connection with 'tools or with the work being done.

Another object of the invention is to provide a helmet the window of which remains opposite the eyes of the wearer during movement of his head into various positions.

Another object of the invention is to provide a helmet that may be adjusted so as to fit anyones head.

Generally stated the invention comprises a helmet consisting of the combination of a pivotally connected head-piece and shield adapted to swing and to abut in two positions whereby the shield may be positioned,

to cover or to clear the face by a toss of the wearers head.

The invention further comprises a helmet consisting of the combination of a headpiece and a window shield movably. connected together and adapted to abut to position the shield in respect to the head-piece whereby the window remains opposite the eyes of the wearer during movements of his head, and the invention further comprises the improvements to be presently described and finally claimed.

The accompanying drawings illustrate one embodiment of the invention chosen for the sake of illustration and description and in them- Figure 1 is a side view illustrating a helmet embodying features of the invention and showing the shield in position for covering the face of the wearer. Fig. 2, is a similar view showing the shield after it has been positioned to uncover the face of the wearer by a toss of his head. Fig. 3, is a front view of the helmet, and Fig. 4, is a sectional plan View of the same.

In the drawings the head-piece 1 is shown to consist of a band or ring, as of metal or other appropriate material, adapted to fit the head of the wearer. As shown the ends of the band overlap and are connected together by slot and bolt connections 2, so that the size of the band can be adjusted to suit heads of different sizes.

3 are bracketsattached to diametrically opposite points on the band 1 and extending downward and outward.

fl is a shield or mask pivoted to the headpiece 1 by means of pivots 5 connected with the brackets 3. Thus the shield or mask may be swung in respect to the head-piece. The shield is provided with an appropriately glazed window 6 and as shown the shield when viewed from the side is sectorshaped and is pivoted to the brackets at the center of the circle of which the sector is a part. As shown and when viewed from the front the shield is somewhat elliptical as shown in Fig. 3. The shield and the head-piece are adapted to collide with each other to limit the swinging motion and to hold the parts in two positions. In the embodiment of the invention shown. in the drawings this is accomplished by providing the band 1 with projecting stops 7 and 8 arranged diametrically opposite each other and at right angles to the brackets 3-and by providing the shield or mask. with an inwardly projecting buffer-stop 9 arranged to collide with the stops '7 and 8 and made of some appropriate material as rubber.

In use the head-piece is fitted to the head of the wearer by suitably adjusting the band 1 by means of the adjustments 2. The wearer then puts the head-piece upon his head and by a toss of his head may cause the stop 9 to rest upon the stop 7 as shown in Fig. 1, and in this case the shield is supported by the head-piece in front of the face of the wearer with the window 6 properly positioned opposite his eyes. When the parts of the helmet are in this position the face of the wearer is protected from light and heat radiating from a sourcea, as indicated in dotted lines 6. Furthermore if the wearer moves his head, as in looking at the work in hand, the window remains opposite his eyes because it is supported from his head in the manner described, and its lower 1 edge is clear of his chest or body, and thereshield swin s back from in front of his face and the bu er-stop 9 rests upon the stop 8,

' as shown in Fig. 2. Of course a toss of the the wearer free to head in the other direction will return the shield from the position shown in Fig. 2 to the position shown in Fig. 1. The fact that the shieldcan be positioned as described by simply tossing the head leaves the hands of attend to whatever work he is doing. The distribution of the weight of the. shield is such that it 'is stable when the bumper or buffer-stop 9 rests upon the stops or rests 7 or 8. a

It will be obvious to those skilled in the art thatmodifications may be made in dc tails of construction and arrangement without departing from the spirit of the invention, hence the latter is not limited in regard to such matters or in any way further than the appended claims and the prior state of I the artmay require.

' signed my name.

What I claim is: e 1 A helmet consisting of the combination of an adjustable head-band provided with front and rear stops, and a swinging shield provided with a buffer-stop for engaging the swinging movement in respect to the latter,

substantially as described. In testimony whereof I have hereunto JAMES H. GRAVELL.
